I have been meaning to write on this topic. I too had this happen every once in a while (wasnt really blue in color but that was looking out of my rearview mirror so not 100% sure). I may have found the trick to it though...at least for my car. \
When I pull in the garage, I let the car idle for about 30 -45 seconds to just calm it down so to speak. I typically drive the car fairly hard when I take it out...so I figured why not let it relax a little before shutting her off. When it was happening every so often, it would be after a drive where I was going pretty hard, pulled in the garage and just shut it down... Since I have been doing this - over the past couple months, I have not had any smoke at all on start up. |

I don't experience smoke at start-up, except when I first start it in the spring and then there is a little bit for a few seconds.
From what I understand though, a little blue smoke at start-up is fairly normal for these cars and nothing to worry about. However, if it starts billowing large amounts of white smoke then shut it down right away and search "AOS failure". |

Smoke on start up is a pretty regular problem on Boxsters, it's the oil separator more times then not.

If there is a concern about the AOS then do the oil filler cap test to confirm or eliminate it as a suspect. |

Most blue smoke on startup is caused by two conditions, one. you start a cold car and move it a few feet and then shut it down, the next start up, you get blue smoke. Second condition, "run the car hard and put it to bed wet" You are at the track, caning the car, then you go into the pit and turn the car off immediately, next startup, blue smoke.
My understanding is that in both of these conditions, oil that has accumulated in the heads, that hasn't gotten back in the sump is the culprit. Solution in both cases is to run the car so the scavenge pumps can do their job and get the oil out of the heads. |

hi ppl
thanks for the help ;) don't think its much to worry about as it doesn't do it a lot, but I'll try the oil filler cap test,,, so i just feel for a vacuum??? again:cheers: |
Yup. the cap will be difficult to pull of if there is a problem and you will feel definite vacuum once it is off.
